6.1.3 Conductive noise
The disk drive shall work without soft error degradation in the frequency range from DC to 20 Mhz injected
through any two of the mounting screw holes of the drive when an AC current of up to 45 mA (p-p) is applied
through a 50-ohm resistor connected to any two mounting screw holes.
6.1.4 Magnetic fields
The disk drive will withstand radiation and conductive noise within the limits shown below. The test method is
defined in the Noise Susceptibility Test Method specification, P/N 95F3944.
6.2 DC power requirements
Connection to the product should be made in a safety extra low voltage (SELV) circuits. The voltage specifications
are applied at the power connector of the drive.
